I have recently changed my front wheel bearings. Once changing my wheel bearings and putting it all back together. It makes a screeching noise when turning left and right. But it seems to be worse when turning left, the noise is slightly less loud when going straight.
I decided to replace the rotors as they were warped as well as the brake pads. But the noise is still very loud, especially at high speeds. It also does make a grinding/screeching noise when pressing on the brakes.
I'm not sure what it could be, can you help?

This is the sound it makes when turning left or braking.

Hi,

For some reason, the video didn't upload. Could you resend it? Also, if you apply the brakes, does the sound change in pitch or volume?

Check to make sure one of the brake rotor backing plates isn't bent and touching the rotor. That can cause a screeching sound.

Let me know.

Here is the video.

I had checked the backing plates, and they are fine. I spun the wheel it hits this sweet spot and grinds. The noise is extremely loud when braking and turning left and slight noise when turning right.

Hi,

I certainly hear it. You indicated with the vehicle lifted, you can turn the wheel and recreate the noise. So, it isn't related to the suspension. It has to be something with the brakes or the new bearings. However, I would suspect the brakes.

Don't laugh, but are the brake pads you used the correct ones? Are the brake rotors the same size as the ones removed?

Let me know.
